Single endpoint overload API

[barneycarroll]

Full patchinko functionality can be achieved with a single API endpoint based on signature sniffing. This is useful for a certain kind of don't-make-me-think cognitive style, whereby the shape of the code is the focus and the diverse patchinko API references are noisy to remember / read. A drop-in extension would read as follows:

const O = (x, ...more) =>
  x
  ? more.length
    ? P(x, ...more)
    : typeof x === 'function'
      ? new S(x)
      : PS(x)
  : D

…such that, testing sequentially:

Overload invocation…	…forks to
O()	D
O(...severalArguments)	P(...severalArguments)
O(function)	S(function)
O(oneNonFunctionArgument)	PS(oneNonFunctionArgument)

This comes at the cost of disabling immutable PS(replacement, patch) since multiple arguments are necessarily forwarded to P. Thus immutable nested property patching would require the more verbose O(definition => O(replacement, definition, patch)).
